Definitions

  • the invention relates to orthopedic-fixation devices and in particular to a clamping coupling for a fixator of the nature disclosed in U.S. Pat. No. 4,312,339 (now Reissue Patent No. Re. 31,809).
  • Said patent discloses an external fixator having a central body part with clamping means at each of the respective ends of the body part.
  • Each of the clamping means is developed (1) to receive and fix in place bone screws or pins and (2) to detachably achieve a ball-joint connection to the central body part, via a bayonet lock or via a threaded lock.
  • the bone screws are connected to the central body part of the fixator.
  • the ball-joint connections arranged at the ends can be angularly adjusted to an angle of about 40°-45° with respect to the axis of the central part of the fixator, which is insufficient in certain cases.
  • the object of the present invention is to improve this indicated type of clamping coupling in such a way, that, without great expense, larger angles can be achieved between the central part of the fixator and the clamping coupling itself.
  • This object which forms the basis of the invention, is achieved by providing a clamping coupling wherein a rotary joint is interposed between the ball-joint connection and the half shell which bears the ball-joint connection proper.
  • FIG. 1 is an exploded view in perspective, partly in longitudinal section, showing a clamping coupling of the invention.
  • FIG. 2 is a similar view to illustrate enhanced angling through use of the coupling of FIG. 1.
  • the drawing shows a clamping coupling 1 consisting essentially of two half shells 2 and 3, which can be fastened to each other by screws 4. Within the half shells 2 and 3 there are recesses 5 which will be understood to serve to receive and fix bone pins, screws or the like.
  • the half shell 3 carries, as a rigid attachment, a ball-joint connection 6 for a bayonet lock or screw lock by which the clamping coupling 1 can be connected to an outer end of a known external fixator.
  • the ball joint connection 6 consists of a ball 9 and a ring 10 which serves for detachable connection to the fixator.
  • the ball 9 of the ball-joint connection 6 directly and rigidly adjoins the half shell 3, but according to the invention, a rotary joint 7 is interposed between these two parts 3 and 6.
  • the rotary joint 7 has a pivot pin 8, which will be understood to include threads by which the angle of the rotary joint 7 can be clamped or fixed, as by wrench application.
  • the ball 9 adjoins the pivot pin 8 via a shank portion 11, and the half shell 3 adjoins pin 8 via a collar or shank portion 12.
  • the ring 10 can, of course, be swivelled on the ball 9, as in the prior art.
